I am trying to connect John Irwin Of Limestone Creek, b 1805 in Washington Co. TN to John Ervin in 1850 census in Jefferson Co. TN. I can follow the family he left behind after that census. 4 sons, Mark, Francis, Abner & Smith. and 4 daughters, Elizabeth Lusk, Martha Amanda Yates, Loretta Kinser and Rachel Mariah Marsh. Would like to know when & where he died between 1850 and 1860 (family was in Polk Co. in 1860) and if his parents were Patrick and Malinda Irwin. HELP!
